Hello, Tess. I wouldn't have believed it myself if my wife didn't insist on it, but if you have a bad case of white kitchen syndrome (wks), then go bold!
We went with a shade of some tuscan green that my wife dreamed up and it worked against our white walls, white cabinets, taupish countertops and light floor.
Here's what we had to work with when we bought the house:
The change is dramatic, yet when standing in the kitchen it feels warm, modern, and yet rich and... uh, I'm out of words. Splash in some cherry wood stuff, deep reds, some tuscan oranges, and you have some boldness.
Anyways, that's my suggestion. If you're gonna go, go all the way!
